浮式生产储卸油装置（FPSO）生产模块的浮式吊装存在巨大挑战，因在作业过程中，典型的管状桁架结构容易发生过度变形。这项研究利用DNV GeniE软件建立了一个有限元模型，模拟了不同海况条件下风、波浪和海流载荷以及起吊瞬间冲击载荷对模块浮吊过程中的影响，并对生产模块结构加固前和加固后的情况进行对比分析。研究结果表明，在起吊作业海况下模块的最大Von Mises应力和变形量分别降低了12.70%和16.43%，在风暴自存海况这一极端海况下模块的最大Von Mises应力和变形量则分别降低了12.22%和6.37%。实验结果证明了加固方案的有效性和可靠性。
Floating lifting of production modules for Floating Production Storage and Offloading (FPSO) units presents significant challenges as typical tubular truss structures are prone to excessive deformation during operations. In this study, a finite element model was developed using DNV GeniE software to simulate the effects of wind, wave, and current loads as well as instantaneous impact loads on the module during the floating hoisting process, and a comparative analysis was performed between the pre- and post-reinforcement conditions of the production module structure. The results of the study show that the maximum stresses and deformations are significantly reduced, proving the effectiveness of the reinforcement strategy and emphasizing the safety and reliability of such operations. The successful implementation of this methodology opens up a promising path for offshore engineering practice and helps to optimize the installation of large offshore modules.
